Question

three angle of a triangle are x, y and 40° . the difference between x and y is 30° the find x and y​

Answer 1

Answer:

x=85 and y=55

Step-by-step explanation:

According to the question,

the angles of the triangle are x,y and 40.

x-y=30.......(1)

x+y+40=180 (angle sum property of a triangle)

→ x+y=140.......(2)

Subtracting (1) from (2),

x=85

substituting this value in (2),

y=55

Hope it helps...

pls mark this as brainliest answer....

Answer 2

Step-by-step explanation:

let the frist and second angle be X

let the frist and second angle be Xthird angle be 40°

let the frist and second angle be Xthird angle be 40° A.T.Q.

let the frist and second angle be Xthird angle be 40° A.T.Q.X+30+X+40°=180°

let the frist and second angle be Xthird angle be 40° A.T.Q.X+30+X+40°=180°2X+70° =180°

let the frist and second angle be Xthird angle be 40° A.T.Q.X+30+X+40°=180°2X+70° =180° 2X = 180° - 70°

2X = 110°

X = 110°/2

X= 55°

X+ 30° = 55° + 30°

= 85°
